New to R; please excuse me if this is a dumb question. I tried to RTFM; didn't help. I want to do a series of regressions over the columns in a data.frame, systematically varying the response variable and the the terms; and not necessarily including all the non-response columns. In my case, the columns are time series. I don't know if that makes a difference; it does mean I have to call

...right call, depending on privacy settings and personal preferences. For VoxSwitch customers, VCCnet will mean that every user can monitor the movement of coworkers in realtime. By using the new APIs, additional data like credit card transactions, fuel consumption in the car, mileage in the air and calories eaten can be reported with a 3D graphical display using HTML5. As an additional service in the VCCnet cloud, Digium will offer extended capacity for your telecommunications platform. When you need more capacity for video calls, 5+1 hd voice conferences and other coming services, including 3D multi...

Hi I think my question might be answered before but i can't find the correct one. Here is the question. I have a data frame from a csv file which contains about 30 variables. lit is like this.

Lately I was reading many articles about using boolean queries for search engine but I haven't seen any complete working demo. Therefore I put together very simple working demo of search engine using boolean query. Feel free to suggest any performance improvement or error while keeping it as simple as possible for understanding. Thanks, -Kevin Duraj http://myhealthcare.com

Ran across a new iPhone app on the the App Store today. It is called DrinkFit and gives you nutritional facts for Beers, Wine Coolers, Cocktails, Liquor, Wine and Mixers. It's pretty cool, gives you calories, carbs etc... for all your favorite drinks so if you are at a bar and want to make a smarter choice, it's a pretty good reference. Check it out on iTunes and www.drinkfitapp.com

Dear All, I hope this is not too off-topic. Essentially, I need to know if there is any R package which can help me with a deformulation project. Suppose e.g. that you know from a chemical analysis the fat, mineral, vitamin, energy [and so on] content of a certain food product. You also know the ingredients of this product (e.g. milk, lactose, vegetable oil) and you know the chemical
